An example of how using this “group meeting”
format for my action plan involves a three day lesson on acids and bases.The class will be broken up into 8 groups.There are four different activities, which means there will be two groups
working on completing each activity.The
groups will conduct the experiment that is assigned to them.Then based on the data they collected, internet research and textbook
information they will be required to answer analysis questions.This information will then be presented to the class using a power point
format.The following are the
topics of the experiments that will be done by each group.

·Acids and their reactions with metals

·Electrical conductivity of acids and bases

·Acid and base indicators

·The neutralization reaction

These
experiments will allow the students to determine some physical and chemical
characteristics of acids and bases.Day
one will be spent on collecting data from the experiments.Day two will be the research phase and finally day three will be the
student presentations.The following sheets should be reproduced and handed out to
student researchers.

Acids and their Reactions With Metals

Directions:

The following is an
experiment that your group should complete by the end of class.Once you have your data collected you will prepare a power point
presentation to explain the results you’ve gathered to an audience who have
not been exposed to this particular experiment.

Procedure:

Place
3 clean test tubes in the rack.

Place
one piece of “non-shiny” zinc in each test tube.

Cover
the zinc in each test tube with a different acid.

Record
observations below.

Repeat
the experiment using copper strips

2.Classify the type of chemical reaction that occurred when the zinc
reacted with each acid.

3.Why did some of the reactions happen at a faster rate than others (*Hint*
compare each acid used, what is different about the acids that were involved in
the faster reactions?)

4.Explain why it is a hazard to store acids in some metal containers, and
not others.

5.When sugar is placed in water, it disappears and is said to have
dissolved.When magnesium metal is
placed in a solution of hydrochloric acid, it also disappears.Explain why the magnesium did not dissolve.

Extension Activity:

An advertisement for a trivia game features the
following question “Do pearls melt in vinegar?” the “correct” answer
given is “yes.”Write a letter
to the trivia company explaining why this is not the case.Use the internet to research the chemical composition of a pearl.Include a simplified chemical reaction demonstrating what is really
happening with the pearl and vinegar.

Electrical
Conductivity in Acids and Bases

Directions:

The following is an experiment that your group should
complete by the end of class.Once
you have your data collected you will prepare a power point presentation to
explain the results you’ve gathered to an audience who have not been exposed
to this particular experiment.

Procedure

Simply defined electricity
is the energy associated with electrons
that have moved from one place to another.A substance that can conduct electricity must have moving negative charges.

Fill
a beaker ¼ of the way full with water.Test the water to see if it conducts electricity.Record observations in the chart below.

Repeat
conductivity test for each substance.Record
observations in the chart below.

Extension Activity:

A popular sport drink, Gatorade, promises to replenish
your body’s electrolytes when you drink it.Use the internet to research which ingredient(s) are contained that make
this drink an electrolytic solution.Also
research how the body uses electrolytes and why they need to be replenished
after exercise.

Acid

Directions:

The following is an
experiment that your group should complete by the end of class.Once you have your data collected you will prepare a power point
presentation to explain the results you’ve gathered to an audience who have

Use
HCl for all the acid tests (accept for the universal indicator than test all
three acids).Use NaOH for all
base tests (accept for the universal indicator than test all three bases).

Place
one drop of acid on each color of litmus paper.Record the color change if any.Repeat this test using the base.Record the color change if any.

Fill
a test tube about ¼ of the way full with acid and fill another ¼ of the

leaf is a naturally occurring acid base indicator.Use the internet to research if there are any other naturally occurring
pH indicators.If so what do they
share in common with the red cabbage?What
are the differences?Then collect
samples of various cleaning solutions, cosmetic solutions, cough syrups, and
beverages that are available in your home.Based on their functions, predict whether these solutions are acidic,
basic, or neutral.Then design an
experiment to verify your predictions.Be
sure to include which indicator you plan to use and why you picked it.
